The air conditioner housing ( 1 ) is defined in that a first air flow path ( 15 ) and a second air flow path ( 17 ) are formed, and in that the air control device ( 9 ) has at least two mixing flaps ( 11, 13 ), a first mixing flap ( 11 ) of which is designed to the first air flow path ( 15 ), and a second mixing flap ( 13 ) of which is assigned to the second airflow path ( 17 ), and in that the mixing flaps ( 11, 13 ) each completely open the assigned air flow path ( 15, 17 ) in a first functional position and completely close it in a second functional position.

BACKGROUND

The invention relates to an air conditioner housing.

Air conditioner housings of the type in question here are used inparticular in conjunction with vehicle air conditioner devices forheating and air conditioning the passenger compartment of a vehicle. Anair conditioner housing of the type in question here is known, forexample, from European Patent Application EP 1070611 A1. It has anevaporation device, a heating device and an air control device which areaccommodated in the interior of the air conditioner housing, in whichair flow paths are formed in order to heat and cool to a greater orlesser extent the air flowing into the air conditioner housing, and todistribute it into various areas of the vehicle. It has been found herethat with only a small degree of structural expenditure it is possibleto provide different areas of the passenger compartment of the vehiclewith airstreams at different temperatures.

The object of the invention is therefore to provide an air conditionerhousing which is small in size while providing the possibility ofsupplying different areas of the passenger compartment of the vehiclewith air streams at different temperatures.

SUMMARY

In order to achieve this object, an air conditioner housing is proposedwhich exhibits the features described herein. It is defined by the factthat a first airflow path and a second airflow path are formed, and thatan air control device has at least two mixing flaps, a first mixing flapof which is assigned to the second airflow path. The mixing flaps arearranged and embodied in such a way that they completely open theassociated airflow path in a first functional position, and completelyclose it in a second functional position. In this way it is possible toinfluence different airflow paths independently of one another usingseparate mixing flaps in such a way that the temperature conditions inthe airflow paths can be set separately.

DETAILED DESCRIPTION

FIG. 1 shows a basic outline of an air conditioner housing 1 in sectionso that the interior space 3 of the air conditioner housing 1 can beseen. The air conditioner housing 1 is demonstrated here in a plan view,the upper side of the air conditioner housing 1 in FIG. 1 pointing inthe direction of travel (arrow F). In the latter there is an evaporationdevice 5, and also a heating device 7, as well as an air control device9. The latter comprises a first mixing flap 11 and a second mixing flap13 which are in the first functional position and thus open two airflowpaths 15 and 17 which are indicated by arrows.

The air which is introduced into the air conditioner housing 1 viablower (not illustrated) flows through the evaporation device 5 and iscooled there. In the illustration according to FIG. 1, air which flowsto the rear from the front is deflected by the first and second mixingflaps 11, 13 and guided past the heating device 7, which is indicated byarrows 19 and 21, so that the airflow paths 15 and 17 are formed. Thecold air leaves the air conditioner housing 1 at the rear, which isindicated by arrows 23 and 25.

The mixing flaps 11 and 13 cover the heating device 7 completely, sothat no air components flow through the latter in the operating mode ofthe air conditioner housing which is illustrated here, and the maximumcooling power is thus made available.

The air conditioner housing 1 is therefore illustrated in an operatingmode in which the air flows exclusively through the evaporation device 5and is cooled there. It is guided completely past the heating device 7via the air control device 9, two airflow paths 15 and 17 being formedin the interior space 3 of the air conditioner housing 1 and leaving theair conditioner housing 1 and being directed into the passengercompartment of a vehicle in accordance with the arrows 23 and 25.

FIG. 1 shows that the heating device 7 is arranged centrally in theinterior space 3 so that the air can be guided around the heating device7 in the region of the airflow paths 15 and 17 to the right and left ofthe heating device 7. It is already apparent from the basic outline thatthe heating device 7 is covered by the mixing flaps 11 and 13 of the aircontrol device 7 in a planar fashion and thus provides only a small airresistance. This leads, on the one hand, to a situation in which the airresistance within the air conditioner housing 1 is relatively low sothat when the blower power remains the same the quantity of air isgreater in the air conditioner housing 1 as illustrated here than in theconventional air conditioner housings, and on the other hand less noiseis generated, which increases the comfort within the vehicle.

The basic outline shows that the heating device 7 has a regular heatingelement 27 which can supply heat via the cooling water of a motorvehicle, and also an electric heating element 29, for example a PCTheater.

The air conditioner housing 1 has a housing 31 which surrounds theevaporation device, the heating device and the air control device.

FIG. 2 shows a basic outline of the air conditioner housing 1 in anoperating mode for maximum heating power. Identical parts are providedwith identical reference numbers so that in this respect reference ismade to the description relating to FIG. 1.

The flow paths 15 and 17 which are illustrated in FIG. 1 are interruptedin the functional position of the mixing flaps 11 and 13 which isillustrated here, and is therefore illustrated only by dots. The mixingflaps are pivoted outward from their position illustrated in FIG. 1 bydrives 33 and 35 which are only indicated here, with the result thatsaid mixing flaps bear in a seal-forming fashion against the wall of thehousing 31, and in the process the rear subsection of the first mixingflap 11 which bears directly against the drive 33 is pivoted to the leftin the counter-clockwise direction, and the rear subsection of thesecond mixing flap 13 which is arranged on the right and is connected tothe drive 35 is pivoted to the right in the clockwise direction. Theends 37 and 39 of the mixing flaps 11 and 13 which face away from thedrive 33 or 35 are guided in a guide, here a slotted guide mechanismwith a running rail 41. Here, the front subsections of the first mixingflap 11 and of the second mixing flap 13 are pivoted with respect to therear subsections, which are assigned to the drives 33 and 35. This ispossible by virtue of the fact that the mixing flaps are embodied in twoparts, and the front subsection of the mixing flaps 11 and 13 which isassigned to the running rail 41 is connected to the rear subsection,which is assigned to the drive 33 or 35, so as to be capable of movingwith respect to said subsection, said connection being preferably bymeans of a hinge. A connection by means of a film hinge is particularlypreferred. The moveable connection between the two subsections of themixing flaps 11 and 13 can also be implemented by injection moulding anelastic material into the connecting region. In this embodiment it isensured that in the connecting region of the subsections air cannot passthrough the mixing flaps 11 and 13. However, it is also conceivable tomake the subsections of the mixing flaps 11 and 13 completely separateand to clip them to one another, for example, in the connecting region.However, the subsections can also be connected to one another so as tobe moveable by means of a common axis. In this case, refinements canalso be selected in which air could pass through the mixing flaps 11 and13 in the connecting region of the subsections. Then, if necessary, itis, on the other hand, also possible to ensure that the connectingregion is sealed in a air-tight fashion.

Owing to this refinement it is possible to pivot the rear subsectionoutward by means of the drive and thus draw the front subsection of themixing flaps 11 and 13 outward against the housing wall 31. The ends 37and 39 of the mixing flaps 11 and 13 are guided in the running rail 41here in such a way that in the second functional position the airflowing through the evaporation device 5 is directed exclusively throughthe heating device 7 in accordance with the arrows 43, 45 and 47, andfrom said heating device 7 into the passenger compartment of the vehiclein accordance with the arrows 23 and 25.

Since the mixing flaps 11 and 13 completely cover the flow paths 15 and17, air cannot enter the passenger compartment of the vehicle bybypassing the heating device 7, so that the full heating power istherefore available.

From the basic outlines in FIGS. 1 and 2 it is clear that the mixingflaps 11 and 13 are of mirror-inverted design and are arrangedsymmetrically in the air conditioner housing 1. The drives 33 and 35 arearranged at a corresponding distance from one another on opposite sidesof the heating device 7.

The air control device 9 which has the two mixing flaps 11 and 13 takesup very little installation space because, as is apparent from FIG. 1,in the first functional position of the mixing flaps 11 and 13, in whichthe air flow paths 15 and 17 are completely opened, they bear againstthe heating device 7 from the outside. At the same time, they form, asit were, a flat gable over the heating device 7 so that said device iscovered in a planar fashion, which provides the abovementionedadvantages. Furthermore, it is apparent that very little installationspace is necessary between the evaporation device 5 and the heatingdevice 7, which is in turn very advantageous for the compact design ofthe air conditioner housing 1.

The drive 33 and 35 can be implemented in different ways. It is decisivethat the rear subsections of the mixing flaps 11 and 13 can be pivotedby the drive 33 or 35 in order, on the one hand, to clear a path for theair stream through the heating device 7 or, on the other hand, to closeoff this air stream completely and clear the air flow paths 15 and 17.

It is possible to divide the air stream which is provided by the heatingdevice 7 and is indicated by the arrows 43 to 47 in FIG. 2, and toensure two separate air flow paths through the heating device 7. It isthus possible to guide a warm air path to the left hand side of avehicle corresponding to the arrow 23, and to direct a warm air currentto the right hand side of the vehicle corresponding to the arrow 25. Thefirst airflow path 15 would then be correspondingly assigned to the lefthand side, and the second air flow path 17 to the right hand side of thepassenger compartment of the vehicle.

If the mixing flaps 11 and 13 are opened and closed in synchronism, whatis referred to as a single-zone air conditioner system is obtained. Ifthe mixing flaps 11 and 13 are opened and closed independently of oneanother by the respectively assigned drive 33 and 35, the temperature onthe right hand side and left hand side of a passenger compartment can beset independently of one another.

In addition it is possible to divide the mixing flaps 11 and 13—whichextend perpendicularly with respect to the plane of the figure—in twowith the result that there are therefore two mixing flaps located onenext to the other on the left and also two mixing flaps located one nextto the other on the right. The mixing flaps are then therefore locatedopposite one another in pairs.

If all four mixing flaps are separated and adjusted independently of oneanother, a four-zone air conditioner system is produced. If two mixingflaps which are located opposite one another are moved independently ofone another and the two other mixing flaps which are located oppositeone another are moved in synchronism with one another, a three-zone airconditioner system is produced.

The heating device 7 and the air control device 9 can be embodied as aunit, as a module. It is therefore possible to easily implementsingle-zone, two-zone, three-zone and four-zone air conditioner systems.

If separate drives are selected for each mixing flap, all that isnecessary to implement the various types of air conditioner is toappropriately configure the means for actuating the drives, that is tosay the drives are actuated completely independently of one another or,if appropriate, mixing flaps which are located opposite one another areactuated in pairs. It is particularly preferred to configure the drivesas stepping motor so that sensitive temperature control or regulationcan be implemented.

It is therefore possible here to move the mixing flaps of the aircontrol device 9 into the first and second functional positions, that isto say to ensure a maximum cooling power and a maximum heating power.Furthermore, it is, of course, possible to assume intermediate positionsin which the air passes out of the evaporation device and in part alongthe flow paths 15 and 17 and is guided in part through the heatingdevice 7 so that a desired temperature can be set at the outlet of theair conditioner system 1, it being possible to apply differenttemperatures to one, two, three or four zones.

FIG. 3 is a sectional view of an air conditioner system 1 with themixing flaps 11 and 13 of an air control device 9 in various functionalpositions. Identical parts are provided with identical referencenumerals so that in this respect reference is made to the descriptionrelating to the preceding figures.

The air supplied by a blower, which is indicated by an arrow 49, passesthrough the evaporation device 5 and, as one alternative, is guided pastthe heating device 7 and flows along the flow paths 15 and 17. In thiscontext it may pass, for example, to the foot well rear left, which isindicated by an arrow 51, or into the foot well rear right, which isindicated by an arrow 53. However, the air can also be guided to therear left for the purpose of ventilation, which is indicated by an arrow55, or rear right for ventilation, which is indicated by an arrow 57.

The arrows 51 to 57 indicate the cold air flows which occur when themixing flaps 11 and 13 are in their first functional position which isalso illustrated in FIG. 1 and the heating device 7 is closed off at thefront in a sealed fashion. For this purpose, a sealing rail whichextends perpendicularly with respect to the plane of the figure can beprovided in a gable region 59, the ends 37 and 39 of the mixing flaps 11and 13 running up against said sealing rail in their first functionalposition. The ends 37, 39 can, of course, also be embodied in such a waythat they bear against one another in a directly sealed fashion in thefirst functional position.

FIG. 3 shows once more the running rail 41 in which the ends 37 and 39are guided when the mixing flaps 11 and 13 are moved out of their firstfunctional position.

The section illustrated here clearly shows the drive 35 of the firstmixing flap 11 and the drive 35 of the second mixing flap 13. The firstmixing flap 11 is represented in two functional positions, namely in thefirst functional position which is characterized by 11 a, in which theheating device 7 is closed off from the evaporation device 5, and in thesecond functional position 11 b in which the flow path 15 is interruptedand all of the air from the evaporation device 15 is directed throughthe heating device 7 and passes to the left hand foot well and to theleft hand ventilation means in accordance with the arrow 61. The air canalso pass to the right hand side of the passenger compartment of thevehicle if a partition wall is not provided here perpendicularly in thecentre plane 63, and said wall has to be provided in the right hand andleft hand sides of the passenger compartment of the vehicle are to havedifferent temperatures applied to them, in either two zone or four zoneair conditioner systems.

The mixing flaps 11 and 13 which are arranged opposite one another inpairs can be actuated in synchronism by means of the drives 33 and 35 orelse separately, as described above, in order to be able to setdifferent temperatures in the right hand and left hand areas of thevehicle.

On the right hand side, the second mixing flap 13 is represented invarious functional positions in order to indicate that the cold airwhich follows the right hand flow path 17 can be decreased to a greateror lesser extent in order to guide more or less air through the heatingdevice 7.

FIG. 3 shows clearly that the first mixing flap 11 has a first componentmixing flap 65 in the lower subsection and a second component mixingflap 67 in the upper subsection and these are connected to one anotherin an articulated fashion such that the angle enclosed between thecomponent mixing flaps 65 and 67 is variable: in the first functionalposition in which the heating device 7 is closed off, the two componentmixing flaps 65 and 67 enclose an obtuse angle with one another, and inthe second functional position in which the first flow path 15 isinterrupted the component mixing flaps 65 and 67 enclose an acute anglewith one another. The two component mixing flaps are therefore attachedto one another in a moveable, that is to say pivotable, fashion,preferably by means of a film hinge. Other embodiments of the inventionhave been explained above.

The second mixing flap 13 is of symmetrical design as is the firstmixing flap 11 so that no more details on this will be given here.

If the air conditioner housing 1 does not have merely two mixing flaps11 and 13 assigned to one another in pairs but instead four, the secondpair is located behind the first pair of mixing flaps which extendperpendicularly into the plane 3 of the figure. In this context it ispossible to assign a common drive to the mixing flaps or a separatedrive to each mixing flap in order to be able to apply air at differenttemperatures to one to four zones of the passenger compartment asflexibly as possible.

FIG. 3 shows once more clearly that the air control device 9 requiresvery little space because in the first functional position the mixingflaps bear directly against the housing 69 of the heating device 7. Ifthe mixing flaps 11 and 13 are moved into their outwardly pivotedposition, they bear in a seal-forming fashion with the connecting regionof the two component mixing flaps against the inner wall of the housing31 so that there is no need here for a further seal-forming device,which significantly reduces the structural expenditure for the airconditioner housing 1 and its complexity.

The mixing flaps 11 and 13 have seal-forming devices on their sideedges, preferably a circumferential sealing edge which bears against theinside of the housing 31 and prevents air from being able to flow pastthe side of the mixing flaps. This ensures a complete separation of theair flows which are formed in the air conditioner housing 1. What arereferred to as creepage openings are also avoided.

In the illustration depicted in FIG. 3, the sealing edges are located onthe side edges of the mixing flap 11 facing the viewer, or theircomponent mixing flaps 65 and 67, and the mixing flap 13, that is to sayits component mixing flaps.

In addition, a sealing edge 70, 70′ can also be provided on the rightand left of the inner wall of the housing 31 along which the side edgesof the mixing flaps 11 and 13 extend, said sealing edge 70, 70′projecting somewhat into the interior space of the housing 31 andserving, as it were, as a stop for the mixing flaps 11 and 13 in theirsecond functional position. For this purpose, the contour of the sealingedge 70, 70′ is adapted to the contour of the first component mixingflap 65 of the two mixing flaps 11 and 13 so that they bear against thesealing edge 70, 70′ in a planar, seal-forming fashion.

The air control device 9 is characterized by a particularly simpledesign. The different temperatures of the air emerging at the outlet ofthe air conditioner housing 1 can be set solely by means of the mixingflaps, of which the mixing flaps 11 and 13 are illustrated here.

FIG. 4 is a perspective view of a mixing flap, for example a mixing flap11 of the air control device 9. The first component mixing flap 65 andthe second component mixing flap 67, which are connected to one anotherin an articulated fashion, preferably by means of a film hinge, can beseen clearly here.

Stub axles 75 and 77 which can interact with a suitable drive which hasbeen described above and has the purpose of activating the mixing flap11 by pivoting the component mixing flap 65 about the rotational axis79, are provided on the left.

In particular in FIG. 3, it becomes clear with respect to the mixingflap 13 that the second component mixing flap 67 is pivoted about apivot axis 81 when the first component mixing flap 65 pivots and ismoved on a circular path about the rotational axis 79. This applies ofcourse also to the mixing flap 11 which is embodied and arranged in asymmetrical fashion.

Two guide pins 83 and 85, which are part of the means of guiding themixing flap 11 and are moved in the running rail 41, can be seen at theend face 37 of the mixing flap 11 located opposite the stub axles 75 and77.

It is apparent here that guides, that is to say running rails, arepreferably present on both sides of a mixing flap.

FIG. 4 shows clearly that the mixing flap 11 is of very simple design.The design illustrated here applies to all the mixing flaps of an airconditioner housing 1 which has been explained with reference to FIGS. 1to 3. It is also apparent that the space required for such a mixing flapis very small so that the air conditioner housing 1 can be very compact.

FIG. 5 shows a sectional view of part of an air conditioner housing 1 ina highly enlarged form. Identical parts are provided with identicalreference numbers so that in this respect reference is made to thedescription relating to the preceding figures.

FIG. 5 shows part of the housing 69 which surrounds the heating device 7which is not illustrated in detail here. The mixing flap 11 isillustrated here in its first functional position so that air flowinginto the air conditioner housing 1 is not guided through the heatingdevice 7. Rather, heating device 7 is closed off completely by themixing flap 11.

The mixing flap 11 has in turn two component mixing flaps 65 and 67which are connected to one another in a moveable fashion. The connectingregion 83 is indicated here by an arrow.

In the closed state of the mixing flap 11 illustrated here, thecomponent mixing flap 67 bears in a planar fashion along its side edgeon a first flap seal 85 so that air cannot flow past the side edges andinto the heating device 7. The first flap seal 85 bears on a sealingedge 70 a and is thus pressed in a planar fashion against the undersideof the second component mixing flap 67 of the mixing flap 11. In thefunctional position illustrated here, the end 37 of the mixing flap 11is pressed against a sealing strip 87 in order to prevent a flow of airthrough the heating device 7 in the closed state of the mixing flap 11.A heating medium, for example the cooling fluid of an internalcombustion engine, generally flows continuously through said heatingdevice 7. For this reason, if the maximum cooling power is requested, itis necessary to prevent the heat from the heating device 7 passing intothe air stream flowing through the air conditioner housing 1.

At the region of the mixing flap 11 which faces away from the end 37, adrive 33 is provided which pivots the first component mixing flap 65,the second component mixing flap 67 then respectively also being moved.In FIG. 5, the first component mixing flap 65 is then in its position inwhich it is pivoted completely to the right and in which the mixing flap11 closes off the heating device 7 in a seal-forming fashion and guidesthe entire volume of air around the outside of the heating device sothat the air flow path 15 which is indicated by the arrow 51, and whichincludes only cold air, is implemented.

In the exemplary embodiment illustrated in FIG. 5, a second flap seal89, which extends from the drive 33 to the connecting region 83, isprovided on the outside of the first component mixing flap 65 facingaway from the heating device 7. If the first component mixing flap 65 ispivoted to the left, that is to say in the counter clockwise direction,by the drive 33, the second flap seal 89 bears against the inner face ofthe housing 31 and against the sealing edge 70.

If the mixing flap 11 is therefore moved in the counter clockwisedirection and entirely into its outwardly pivoted position, the firstairflow path 15 is closed off by the second flap device 85 in a sealedfashion so that cold air cannot flow out of the air conditioner housing1. The entire air stream is therefore guided through the heating device7.

It becomes apparent here that, as indicated by a dashed line 91, thesecond flap seal 89 which is provided in the region of the firstcomponent mixing flap 65 can also be omitted and instead be provided onthe sealing edge 70. As a result, the first component mixing flap 65acts exclusively as an activation element for the second componentmixing flap 67 and no longer has to contribute to sealing the first airflow path 15.

FIG. 5 also shows that the first flap seal 85, which is provided atleast in the region of the second component mixing flap 67, can extendbeyond the connecting region 83 so that in the first functional positionillustrated here the first component mixing flap 65 also bears in partagainst the first flap device 85. As a result it is possible, asexplained above, also to construct the connecting region 83 in such away that air can always flow through it. This is not disadvantageousbecause in the case illustrated here, in which the heating device 7 isto be sealed off, the first flap device 85 extends over the connectingregion 83 and thus closes it off from the inside in a seal-formingfashion.

When the first component mixing flap 65 is pivoted by the drive 33, theconnecting region 83 is moved on a virtual circular path 93. Since thedrive 33 is arranged to the left of the connecting region 83, the end ofthe second component mixing flap which faces the connecting region 83 islifting from the flap seal 85 as the first component mixing flap 65pivots. This significantly reduces wear to the flap seal 85 becauseduring a pivoting movement of the first component mixing flap 65 thecomponent mixing flap 65 is virtually moved only by one end 37 along theflap device 85. On the other hand, when the heating device 7 closes, theconnecting region 83, and thus also the end of the second componentmixing flap 67 facing away from the end 37, is pressed in a sealedfashion against the flap seal 85.

During a pivoting movement of the first component mixing flap 65 to theright, that is to say in the clockwise direction, the end 37 of thesecond component mixing flap 67 is also pressed against the sealingstrip 87, thus also ensuring that the heating device 7 is closed off ina sealed fashion in this case.

After all the above, it becomes clear from FIG. 5 that the mixing flap11 can be influenced in various ways: it is possible to provide one flapseal 85, 87 in each case directly on the component mixing flaps 65 and67. However, said flap seals 85, 87 may also be provided on the sealingedges 70 and 70 a. In particular if the second flap seal 89 is notprovided on the first component mixing flap 65 but rather, as indicatedby the line 91, on the sealing edge 70, the first component mixing flap65 can serve exclusively as an activation element for the secondcomponent mixing flap 67. This closes, as is apparent, for example, fromFIG. 3, the first flow path 15 by the end 37 bearing against the flapseal 85, on the one hand, and by the connecting region 83 bearingagainst the inside of the housing 31, on the other side.
